  • 1 Answer can take off the airbox cover without having to rip the whole plastic thing off of the seal(you'll see what I mean). This will give you enough room to see the top of the plug. At this point you'll need to take off the plastic thing which directs the air into the box (left side of the bike) so you can reach under the plug to put the new one in place and to take off the leads. I'm not in my garage but you'll need a 360 degree socket swivel and an extendor to change that out and get the right torque. You can pick up one of these extendor kits at most hardware stores.
Good luck

2002 harley electra glide front spark plug turns black

A blackened spark plug is a sign of a rich air/fuel ratio or a misfiring plug. You stated that you changed the coil and wires, but did you change the plugs? Spark plugs, even new ones, can, and do, go bad (excessive internal resistance). Make sure that the plugs are also the correct part number for your application, as they could be of the wrong heat range for your bike. I have even heard of guys using a colder plug in the rear cylinder and a hotter plug in the front cylinder because the front cylinder tends to run a little cooler than the rear (increased air flow in the front).

Spark plugs

Although the problem could indicate a (potentially) expensive electrical fault. It is worth trying the simple (and cheap) fixes first:
Have you tried swaping the Spark plugs (front to rear) If the fault moves with the plug, then A new set will get you sorted.
(Spark plugs may appear OK off the bike, but can break down when under compression)
Can't guarantee that this will work, but well worth a try.

How and what do i need to do a major service on my 200b ZX 10R?

hi you dont say how many miles the bike has done, the normal things to replace are oil, oil filter, air filter and spark plugs, you may want to check all wearable items like chain and sprockets, brake pads, brake fluid change front and rear, poss fork oil change, heck tyre condition, steering head bearings , lubricate all moving parts including chain, cables, footrests, etc, most time consuming part changing the spark plugs no1 and no 4 plugs require removal of engine mount, suport engine as it can move just enough to make refiting the bolts arkward

How hard is it to change plugs in an 03 buell firebolt xb9r

Well, it depends on how nimble your fingers are!

for the front plug: remove the shifter side air scoop. . You should be able to get an open end wrnch up onto the plug pretty easily. When it is loose remove the spark plug boot from the plug. Next put the new plug up into the head and start the threads gently BY HAND!. This is an aluminum head and the plug has steel threads. You do not want to strip those threads. Once the plug is finger tight give it another 1/6 to 1/4 turn with the open ended wrench. then reach up with those nimble fingers (or a pair of plug boot pliers) and slip the plug wire back on until it seats.

The rear head requires the removal of the inner and outer airbox. you can then reach down and remove the plug wire. removing the plug requires a plug socket, an extension 6-8 inches and either 1 or 2 swivels depending on how close to the frame the extension is when on the plug. back it out and remove. I recommend using a piece of rubber tubing to hold onto the rear plug in order to carefully start the plug into the threads (see above). Then once it is "finger tight" remove the tubing and use the socket to tighten properly.

Then you re-assemble your bike and go for a ride. It sounds harder than it is, and with a bit of practice we were doing this in between rounds on the race bike in minutes.
